Received Received - Intake
Authorization Bypass in monetr Allows Soft-Deletion of Transactions

Publication date: 2026-04-08

Last updated on: 2026-04-08

Assigner: GitHub, Inc.

Description
monetr is a budgeting application focused on planning for recurring expenses. Prior to 1.12.3, a transaction integrity flaw allows an authenticated tenant user to soft-delete synced non-manual transactions through the transaction update endpoint, despite the application explicitly blocking deletion of those transactions via the normal DELETE path. This bypass undermines the intended protection for imported transaction records and allows protected transactions to be hidden from normal views. This vulnerability is fixed in 1.12.3.

Mitigation Strategies

To mitigate this vulnerability, upgrade the monetr application to version 1.12.3 or later, where the issue has been fixed.

Executive Summary

This vulnerability exists in the monetr budgeting application before version 1.12.3. It involves a transaction integrity flaw where an authenticated tenant user can soft-delete synced non-manual transactions by using the transaction update endpoint. Normally, the application blocks deletion of these transactions through the standard DELETE method, but this flaw allows bypassing that protection. As a result, protected imported transaction records can be hidden from normal views.

Impact Analysis

The vulnerability allows an authenticated user to hide certain transaction records that should not be deleted. This can lead to inaccurate financial data being displayed or reported, as important imported transactions can be soft-deleted and thus hidden from normal views. This undermines the integrity of budgeting and financial planning within the application.
